Summary
128GB of unified memory and NVIDIA’s RTX Spark N1X let HP’s OmniBook Ultra 16 run 70B and even 120B language models locally, positioning it as a niche workstation for AI developers and technical artists.
The 16-inch laptop pairs a 20-core Arm CPU with a 6,144-core Blackwell RTX GPU, a 3K 120Hz OLED display, and broad I/O, giving users CUDA-capable Windows-on-Arm hardware without relying on cloud compute.
That capability comes with trade-offs: the chassis weighs 4.89 pounds, fans and surface heat rise under sustained inferencing, and battery life can fall from about eight to nine hours of light use to roughly two hours under heavy AI workloads.
Pricing keeps it firmly in enterprise territory—HP’s 128GB, 1TB configuration lands around $5,309 and the 2TB version reviewed reaches about $6,159, while the memory is soldered and not upgradeable.
The review scores the machine 9.6/10 and argues it has little direct competition for professionals who need large-model, on-device AI work with sensitive data kept off the cloud.
